No problem! I hope it helps! One of my favorite speed testing sites is http://www.speedtest.net
It's very reliable, and it stores results for your IP. You set your download AND upload to 2700? This is a good starting point, and you may be able to fine tune it some more by averaging your capacity over time. Again, if this is a business you are setting this up for, make sure you also know if the phones use the paired T1's.
A good stress test on your shaper is to ALLOW P2P traffic and attempt to download multiple Ubuntu (for example) torrents. The goal is to saturate your pipe and to start sending out as many ACKs as possible to make sure you have everything tuned correctly. You have the added benefit of also testing out other queue reservations, to make sure the saturation isn't bringing everything else down to it's knees. (Like system related traffic, mail server, web server, vpn server, etc) P2P traffic is a good way to do this, since you are connected to so many peers with a lot of data coming down.
Then when you're done, PENALIZE P2P traffic in it's lower priority queue. :)
